OBJECTIVETo discuss the therapeutic effect of thenar perforator flaps for the narrow cicatricial contracture at thumb and the first web.

METHODSFrom Aug. 2010 to Jan. 2012, 9 cases with narrow cicatricial contracture at thumb and the first web, were treated. The defect size after releasing the contracture ranged from 8 mm x 20 mm to 15 cm x 30 mm. The bilateral thenar perforator flaps beside the wound were designed which size was 10 mm x 25 mm to 15 mm x 35 mm. The wounds at donor sites were closed directly.

RESULTSAll the 9 flaps survived completely with primary healing. The patients were followed up for 6-18 months. The flaps had soft texture and good appearance. The shape of flaps and function of the fingers were satisfied after 6-18 months of follow-up. There was no scar contracture at incisions in thenar. The thumb motion was really normal. The abduction of first web was 70 degrees - 90 degrees degrees.

CONCLUSIONSThe thenar perforator flaps is one of the ideal methods for the treatment of narrow cicatricial contracture at thumb and the first web. The main artery is not sacrified.

Objective To analyze the clinical value of anterior decompression and fusion with internal fixation and simple decompression in the treatment of cervical vertebral multilevel degeneration.Methods Selected 40 patients with cervical degenerative changes in our hospital from 2012 to 2014,and 20 patients of them underwent anterior decompression and fusion with internal fixation while the other 20 cases took simple decompression.All the patients were well followed up,and the clinical therapeutic effect of the two groups were compared and analyzed.Results After operation,the VAS score and JOA score showed that the scores of the patients underwent anterior decompression and fusion with internal fixation were significandy improved compared with the simple decompression group,and the difference was statistically significant(P ＜ 0.05).Compared with the simple decompression group,the cervical curvature and the curvature of the surgerysection in the anterior decompression and fusion with internal fixation group were significantly improved,especially in the first year after surgery (P ＜ 0.05).The cervical spine joint activity of the two group were improved in the first year after surgery,and the difference was significant (P ＜ 0.05),but there was no significant difference in the degree of cervical joint activity at the last follow-up(P ＞ 0.05).The anterior decompression and fusion with internal fixation is better than simple decompression in the degree of cervical joint activity with statistical significance (P ＜ 0.05).Conclusion The clinical effect of anterior decompression and fusion with internal fixation in treatment of multiple segment degeneration of cervical spine is better than that of simple decompression,it can meet the clinical requirements of biomechanics.

Objective: To observe the clinical efficacy of acupuncture plus MOTOmed intelligent motor training in treating children with spastic cerebral palsy, and analyze the effects on lower limb motor function, intelligence development level, immune function and cerebral hemodynamics.Methods: A total of 42 children with spastic cerebral palsy were selected as the observation objects, and enrolled into the observation group. Another 42 cases treated in the same period were selected as the control group. Both groups received MOTOmed intelligent motor training, and the observation group was given additional acupuncture therapy, and the control group was given additional conventional rehabilitation treatment. After 2 consecutive treatment courses, the psychomotor development index (PDI) and mental development index (MDI) of Children's Developmental Center of China (CDCC) scale, the scores of gross motor function measure (GMFM) scale and modified Ashworth scale (MAS), and the changes in CD3+, CD4+, CD8+ and CD4+/CD8+ were observed. The peak systolic velocity (PSV) and mean flow velocity (MFV) of the anterior cerebral artery (ACA), middle cerebral artery (MCA) and posterior cerebral artery (PCA) were observed and measured. The clinical efficacy was evaluated. Results: Compared with the same group before treatment, the scores of GMFM, PDI and MDI, levels of CD3+, CD4+ and CD4+/CD8+, PSV and MFV levels of ACA, MCA and PCA in both groups were significantly increased after treatment (all P<0.05), while the CD8+ level had no significant change (both P>0.05). After treatment, the total effective rate of lower limb spasm in the observation group was 90.5％, significantly higher than 71.4％ in the control group (P<0.05). The scores of GMFM, PDI and MDI, the levels of CD3+ and CD4+, PSV and MFV, and the levels of ACA, MCA and PCA in the observation group were all significantly higher than those in the control group (all P<0.05). There were no significant differences in the CD8+ level and CD4+/CD8+ between the groups (all P>0.05). Conclusion: Acupuncture plus MOTOmed intelligent motor training has a better clinical efficacy than conventional rehabilitation plus MOTOmed intelligent motor training in treating children with spastic cerebral palsy, and is also superior in improving lower limb motor function and the level of intellectual development. And the mechanism may be related to the improvement of cerebral hemodynamics.

This study is to investigate the protective effect of longistyline A against corticosterone-induced neurotoxicity in PC12 cells. While PC12 cells were exposed to 100 micromol x L(-1) corticosterone for 48 h, cell survival rate was reduced and lactate dehydrogenase (LDH) release increased. In parallel, corticosterone caused significant elevations of DNA fragmentation, [Ca2+]i and caspase-3 activity. However, when the PC12 cells were incubated with longistyline A (4.0, 8.0 and 16.0 micromol x L(-1)) in the presence of 100 micromol x L(-1) corticosterone for 48 h, the effects were evidently alleviated, but dose-dependent manner was not obvious. In summary, longistyline A could generate a neuroprotective effect against corticosterone-induced neurotoxicity in PC12 cells possibly by decreasing [Ca2+]i and caspase-3 activity.

OBJECTIVETo establish the chromatography-efficacy relation method for analyzing the anti-inflammatory activity of Qizhi Weitong particles, in order to lay a foundation for quality control and pharmacodynamic evaluation of traditional Chinese medicine compounds.

METHODOn the basis of a full-time multi-wavelength fusion fingerprint of Qizhi Weitong particles, the latin hypercube sampling was used to divide six herbs in Qizhi Weitong particles into groups of different proportions to determine their inhibition ratios of TNF-alpha, IL-6 and NO released by LPS-induced RAW264. 7 cells. Pharmaeodynamic data and chemical information of HPLC fingerprints of each group were analyzed with the gray correlation method to get the anti-inflammatory effect of each chromatographic peak, and then fitted with BP neural network to establish the chromatography-efficacy relation.

RESULTThere were 25 peaks closely related to the anti-inflammatory activity. With the 25 peaks as input items, the 3-BP network was adopted to establish the neural network model for anti-inflammatory effect of Qizhi Weitong particles.

CONCLUSIONWith an error of less than 7%, the model could better fit with the complicated non-linear relation of the compound, and applied in studying the chromatography-efficacy relation. In this study on the chromatography-efficacy relation, a new method is established to evaluate the anti-inflammatory activity of Qizhi Weitong particles. It is of practical significance as an effective approach for controlling quality and exploring the material basis for efficacy of traditional Chinese medicine compounds.

OBJECTIVETo investigate the expression profiles of serum Golgi protein-73 (GP73) in liver cirrhosis and primary hepatic carcinoma (PHC) and determine its clinical value for differential diagnosis.

METHODSSerum protein expressions of GP73 and alpha-fetoprotein (AFP) were detected by enzyme-linked immunosorbent assay and chemiluminescence assay, respectively, in patients with PHC (n=80), liver cirrhosis (n=65), and healthy controls (n=50). Inter-group changes were assessed by Kruskal-Wallis test, and significance of these differences was assessed by Mann-Whitney test. A receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic efficiency and determine the cut-off values for GP73 and AFP. Sensitivity and specificity were compared by the Chi-squared test. Correlation between serum GP73 expression and clinical parameters was determined by Spearman's rank correlation analysis.

RESULTSThe PHC group showed significantly higher serum GP73 (282.0 mug/L) than the liver cirrhosis group (211.8 mug/L) and control group (58.3 mug/L) (H = 93.30, P less than 0.01). For differential diagnosis of PHC and liver cirrhosis, the cut-off value was 318.1 mug/L for GP73 and 13.4 mug/L for AFP. Sensitivity of GP73 was lower than AFP (45% (36/80) vs. 65% (52/80); X2 = 8.02, P less than 0.05). Specificity of GP73 was lower than AFP but no significance was found (83.1% (54/65) vs. 87.7% (57/65); X2=0.27, P more than 0.05). The areas under the ROC curves were not significantly different between GP73 and AFP (0.65 (95% confidence interval (CI): 0.54~0.72) vs. 0.75 (95% CI: 0.67~0.83); Z = 1.88, P more than 0.05). The area under the ROC curves increased but not significantly (0.80 (95% CI: 0.73~0.88) vs. 0.75 (95% CI: 0.67~0.83); Z=2.61, P more than 0.05). Serum GP73 was correlated with liver cirrhosis (r=0.27), vascular invasion (r=0.29), and TNM staging (r=0.27) (all P less than 0.05), but not with sex (r=0.13), age (r=0.10), enhanced AFP (> 13.4 mug/L; r=0.03), tumor size (r=0.18), or distant metastasis (r=0.04), all P less than 0.05.

CONCLUSIONSerum GP73 and AFP have comparable diagnostic efficiency, but the sensitivity of AFP is superior for differential diagnosis of liver cirrhosis and primary hepatic carcinoma. Elevated serum GP73 may be correlated with liver tumor load and aggressiveness.

OBJECTIVETo investigate the clinical epidemiological characteristics and the major causes of primary liver cancer (PLC) in Xinjiang region.

METHODSThe clinical epidemiological information on the first page of case history of 3602 PLC patients, which were diagnosed in our hospital from January 2002 to December 2010, were retrospectively reviewed and analyzed.

RESULTSAmong the 3602 cases, the men/women gender ratio was 3.72:1; The proportion of Han, Uighur, Kazakh, and other nationality (Hui, Mongolian, Manchu, Xibo nationality) was 81.95%, 9.30%, 4.14%, 2.89%, and 1.72%, respectively. The comparative difference between Uighur and Han nationalities was significant (P < 0.05). The hepatitis virus detection results showed that HBs-Ag was positive in 1680 cases (59.57%), HCV-Ab was positive in 229 cases (9.41%). Virus detection was negative in 888 patients (24.65%). The hepatitis B virus positive rate in Uygur patients was 36.13% and in Kazakh patients was 40.37%, both significantly lower than that in patients of Han nationality (63.18%, P < 0.05).

CONCLUSIONSIn Xinjiang region, the infection rate of hepatitis B virus in Uygur and Kazak people is significantly lower than that in Han people. The distribution of gender and age does not differ significantly among different nationalities, compared with those in other regions. The prevalence of primary liver cancer in Xinjiang region has certain regional characteristics and features.
